The photo shows a Needham gate in Padauk timber this timber is  currently not available (Iroko would give a similar look but is not as consistent in colour, varying from light golden to a rich red often within the same gate / side panel).
Needham gates have a visible base rail which can be clearly seen in the photo, this has been matched in the side panel too. Raised Manors are standard on Needham gates  - these are when the stiles rise above the top line of the gate, however the customer chose the non standard option of having  a smooth top line to keep a continuous flow over both the gate and side panel. 

A similar effect can be achieved with Glemham or Deben gates and in a variety of timbers from Scandinavian redwood, Larch, Iroko and Oak. Covering a wide variety of tastes, budgets and finishes.
Side panels and Gates are made to measure so can be adjusted to suit any situation.
